What extra history does the dealer review print?
The dealer review prints that in 1994 CGI became the first manufacturer of hurricane windows and doors to offer laminated glass that met Miami-Dade County impact standards, and that existing NOA approvals remain valid after the brand ending. Those are dealer-page strings, not Miami-Dade NOA digits invented here.
